Why are African Americans more likely to have high blood pressure and diabetes than whites?

What an impolite way to ask for information.

Do you think we work for you or something?

The diet and living conditions of poverty. If one is black, one is more likely to be ill.

I think it is very and very personal. People (white, black, orientals...) can have problems with health, but it's not something that they will have.
Like if I say that a friend of mine is black, he is fat and have diabetes, that doesn't mean that you, black, you will have the same.
White people also have a lot of problems, but of course there are perfectly healthy people. All depends first of all from the diet, and then from your health problems (or genetic problem).
